I was trying to recharge the disposable one-time single-use power bank (the eco-disaster) from this video:
Despite being designed as a one time charger, it appears to contain a rechargeable Li-Ion or Li-Pol cell.
Warning: Batteries (rechargeable or non-rechargeable) may be dangerous. Risk of leakage, fire or explosion at any time, especially when in use, in case of overcurrent, short circuit or when being recharged.
